TO ALL WHOM IT MAY CONGERN: p

Be it known tha-t LJQHN TIPTON, of Malaga, in the county of Monroe, und State' of Ohio, here invented n' new and improved Self-Sustaining Hoof-Expander; and do hereby declare the following to be :t full, clear, and exact description of the sume, reference being had to the accompanying drawings, forming part ot' this specification, and in which- I Figure 1 is a. perspective View of my invention.

Figure 2` is e side elevation of the same. v

In this invention two pieces of metal are mede to tit into the cavityolongside of the fregar of e horses foot, and nre then expanded by means of n screw-rod connecting them. i l

Thisinvention is designed .to expend the hoot' of a. horse in case of its contraction from corns or other diseases of the foot, or from any other cause. i v Y In order that others skilled in the art'to which my invention apperteins may be enabled to make and use the seme, I will proceed toV describe it in detail. l Y v l In the drawings, A represents n piece ofmetal, hai-ving, at one extremity, nroughened outer edge, a, and its other extremity formed into e sha-nk to receive the connecting-rod B, andthe adjusting-rod C. A is another piece of metal, of similar shape, but working in the opposite direction npon the connecting-rod B. The rod B is firmly zlttztched to the shrink of the piece A,`and upon it the piece Afslides Ifreely, the 'rod passing through :t lateral hole in its shank. C, the adjusting or expendinguod, is e. stout rod of iron, provided with e. screwthread, c, at one end Working in one direction, end another screw-thread, c', :it the opposite end, working in the opposite direction. It has also a handle, c, by which it can be vturned with as much force as may be required. The pieces A and A' are made-of snitnble'sizleand shape to t into the cftvities on each side of the frog of n. horses foot, the Toughened edges ct a beingl placed towards the toc, and the Shanks of the pieces A A being placed at' the heel. By means of the screw-rod C the pieces VAA. are then screwed apart, as fer as may bo necessary, and the horses hoot` expanded to the extentrequired. The screw-threads c c', running in directions opposite to eachother,I screw the pieces' A A apart equally and uniformly, and thereby insure the uniform expansion of the hoof. I A j The instrument thus.forn1ed is cheap, simple, anddureble, and has been'liollyl tested end found to beA admirably adapted tothe purpose required.

Having thns described my invention, what I claim as new, and desire to secure by 'Letters Patent, isrlhe instrument abovevdescribed, vwhen constructed and used substantially es and for the purpose speeied.V
